WINDING AND SETTING LIECHANISM FOR CLOCKS.

Application filed June 5, 1912.

To all whom 2'25 may concern:

Be it known that we, ELMER E. XVILKIN- son and SAUL AnoNsoN, citizens of the United Sta tes of America, and residents of the borough of Brooklyn, county of Kings, city and State of New York, and borough of irlanhattan, city, county, and State of New York, respectively, have invented certain new and useful Improvements in lVinding and Setting Mechanism for Clocks, of which the following is a specification.

Our invention relates to winding and setting mechanism of clocks and like time pieces, and comprises mechanism whereby the clock may be wound, and the hands set, by rotating back and forth the clock movement.

The improved clock herein described is particularly adapted for mounting on the dash-board of an automobile or other vehicle, or for mounting on a bulk-head or partition of a boat. It is, however, convenient for use in various other locations.

The object of our invention is to provide simple and easily operated means for winding and setting clocks, and which shall not comprise any separate winding or setting member, such as a key, nor shall it comprise a projecting stem or the like.

lVe will now proceed to describe our invention with reference to the accompanying drawings, and will then point out the novel features in claims.

In the drawings: Figure 1 shows a front elevation of the clock, and Fig. 2 a central longitudinal section of the cases of the clock, the mechanism being shown in the main in elevation. Fig. 3 shows a transverse section on the line w.% of Fig. 2, looking toward the rear. Fig. 4: shows a rear elevation of the movement case. Fig. 5 shows a transverse section of the line 00-42 of Fig. 2, looking toward the front. Fig. 6 is a view similar to Fig. 2, except that the movement case is shown drawn out into hand-setting position.

In the drawings 1 designates the base plate of the clock and 2 the outer case secured to and substantially forming a part of the base.

3 designates the inner or movement-case, within which is mounted the dial 4, the

movement plates 6 and 7, and the main-- spring barrel 8.-

lVe have not in the drawings indicated all of the gearing for transmitting motion from the main-spring to the hands of the clock, as such gearing forms no portion of our present invention.

The inner or movement-case 3 has a back or base 9 provided with an annular flange 10, the purpose of which will be explained hereafter. This movement case is arranged to be rotated back and forth within the outer case 2, its motion being limited by a pin 11 secured to a centrally bossed plate 12, itself secured to base 1, this pin 11 projecting through a slot 13, in the back 9 of the movement-case 3. A helical spring 14 is connected at one end to this pin 11, and at its other end is provided with an outturned projection 15 engaging one side of an opening 16 in back plate 9, the arrangement being such that when the move ment-case 3 is rotated clockwise, such rotation is opposed by a spring 14, and as soon as the movement-case is released, said spring 14 will move the movement-case back to first position.

17 designates the main springqvinding arbor. This arbor has a bearing in plate 12, above mentioned, and in the rear movement plate 7, and has secured to it a ratchet wheel 18, the ratchet 19 of which is pivoted to the plate 12 at 20. Said ratchet is provided with the usual ratchet spring 21, and with a tooth 22, to engage the teeth of the ratchet wheel 18. The arbor 17 is further provided with a gear wheel 23 which, when the parts are in normal position, is in mesh with the gear 2 1 on the arbor 25 of the main-spring, the latter being, as usual, with in the barrel 8.

The movement case 3 is provided with a screw-connected ring 3*, by which said movement case may be rotated for winding the clock or for setting the hands. This ring 3 carries the usual glass 8 which protects the hands and dial of the clock. During clockwise rotation of the movement case one of the teeth of ratchet wheel 18 is engaged by the tooth 22 of ratchet 19 and the ratchet wheel is held stationary; but during the backward rotation of the movement case the ratchet wheel slips idly under the ratchet: the result being that motion is transmitted to gear 24 and the spring is wound. For setting the clock the entire movement case 3 with the movement within it, is arranged to be drawn forward so as to bring a pinion 26 on a shaft 27 into mesh with a gear 28 on the main spring winding arbor 17. To so pull the movement case 3 forward, the ring 3, screw connected to the case 3, as shown particularly in Figs. 2 and (3, is grasped and drawn forward. Fig. (3 shows the movement case in the resulting setting position. While this movement of the movement case draws the gear 26 into mesh with the gear 28, the nine movement draws the winding gear 2:4: out of mesh with the winding gear The result is therefore to throw the winding gear out of action and throw the setting mechanism into action; for shaft 27, upon which pinion 26 is mounted, connects with the usual hand-driving train 29 located between the front movement plate 5 and the dial 4.

When the movement case 3 is drawn into the forward or setting position shown in G, the flange 10 on the back 9 of the movement case 3 embraces the ratchet 19 of the winding mechanism so closely that the tooth 22 of that ratchet cannot move out of engagement with the teeth of the ratchet wheel 18. Said flange, by so holding the ratchet in engagement with the ratchet wheel, in effect locks the gear wheel 28 stationary, against movement in either direction, so that rotation of the movement case when in the position shown in Fig. 6, effects rotation of the pinion 26, shaft 27 and the operation of the hand-driving train 29. Normally the movement case is held in the position shown in Fig. 2 by a spring 30 shown particularly in Figs. 2 and 5; the arms of which spring tend to press the back of the movement case 3 backward. During the operation of setting the hands, the movement case 3 is held forward in the position shown in Fig. 6, against the tension of this spring; and as soon as the movement case is released, the spring 30 throws it back into the position shown in Fig. 2.

The operation of the winding and setting mechanism is therefore as follows: To wind the clock the ring 3 is rotated forward and back through an angle represented by the slot 18, or through any convenient smaller angle; and during each forward or clockwise rotation of the ring 3 (and therefore of the movement case 3 and the movement within it) the ratchet 19 engages the teeth of ratchet wheel 18, and holds said ratchet wheel stationary, so causing gear 23 to impart motion to gear 24 and to wind the main spring, while during the backward rotation said ratchet 1.9 slips over the ratchet wheel.

5 stationary. To set the hands, the moven'icnt case is drawn forward by means of the ring 3 has disconnecting gears and 2-11: of the spring winding train and inter meshing gears 26 and 28 of the hand setting mechanism, and then, by rotating ring 3 in either direction, as circumstances may require, the hands are set, after which the rin 3 is released, and the spring 30 draws the movement case back to the position shown in Fig. 2.
